INSIDE-TRIMMING MACHINE FOR TRIMMING WOODEN HANDLES FOR TOOLS AND THE LIKE.

Application filed September 1, 1911.

To all whom it may concern:

Be it known that I, JOSEPH C. KIMERER, a citizen of the United States, residing at Paris, in the county of Lamar and State of Texas, have invented certain new and useful Improvements in Inside-Trimming Machines for Trimming \Vooden Handles for Tools and the like, of which the following is a specification.

My invention relates. to trimming machines and more particularly to machines for trimming the inside portions of Wooden tools or handles, such as handles for spades, shovels, and like articles, and the object is to provide a simple machine which will be highly efficient and extremely accurate in trimming the curved interior portions of tools and similar parts of tools or handles, and which machine will be simple in operation and provided with means by which the machine is adjusted into and out of opera tive positions.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application and specification.

Figure 1 is a plan view of the machine. Fig. 2 is a side elevation of the same. Fig. 3 is a detail view of the trimming blade. Fig. 4 is an end elevation of the machine from the left side of Fig. 2. Fig. 5 is a view of a part of a spade handle and Fig. 6 is a section of the part which is trimmed by the machine. Fig. 7 is a cross section of the blade 11.

Similar characters of reference are used to indicate the same parts throughout the several views.

The machine is provided with a frame having a platform 1 and upright legs or posts 2 on which the platform is firmly supported. The platform is bifurcated, for purposes hereinafter explained, and a crossbar 3 at the bifurcated end of the platform 1 makes the platform 1 rigid. Other braces are provided in the cross-bars 4 and 5. An oscillating blade carrier consisting of a bar or frame 6 pivotally mounted on cross bars 4 and 7, a blade holder 8, a spring controlled chucking bar 9, and guide pin or rod 10. The blade 11 is rigid with the Specification of Letters Patent.

holder 8 and the bar 6 has a socket into which the lower shank 12 enters loosely. The blade is prevented from turning in the holder 8 by a key 13. The blade 11 is curved to the curvature of the article to be trimmed and has two cutting edges, one on each side, so that the blade cuts in moving both ways. It is apparent that the blade 11 can be varied in form to adapt the same for cutting or trimming different shapes. The rod 9 is the chucking bar, but the actual chucking is accomplished by the spring 1 1 which holds the blade 11 in operative position and brings the same back to operative position, as hereinafter explained. The car rier is oscillated or vibrated by a crank wheel 15 and a pitman rod 16 which is pivotally connected to the wheel 15 and to a lug 17 which is rigid with the bar 6. The crank wheel 15 is driven by the shaft 18 which is journaled in bearings 19 and 20 which are rigid with the platform 1. The shaft 18 is driven by a pulley 21. The pulley wheel 21 is provided with means for driving from power above. An idle pulley wheel 22 is journaled in arms 23 which are pivotally connected to shaft18. This pulley wheel 22 is used to tighten a belt on the pulley wheel 21. A foot lever 24 is connected to the arms 23 for operating the idler 22. A brake 25 is also provided and engages a wheel 26 which is rigid with shaft 18. With the mechanism thus described the blade 11 is vibrated or oscillated for cutting or trimming purposes.

Means are provided for holding articles to be trimmed and for inserting and removing the articles. A shiftable frame 27 is mounted on the frame 1. Guides 28 prevent lateral displacement of the frame 27 The frame 27 is movable on the frame 1 by a lever 28 which is pivoted on the frame 1 at 28". A link bar 29 is pivotally connected to the frame 27 and to the lever 28. By means of the lever 28 the frame 27 can be reciprocated on the frame 1. The frame 27 carries the means for holding the article to be operated upon. The article to be operated upon is clamped by a pair of arms 30 and 31 which are pivotally mounted on studs 32 which are rigid with the frame 27. Standards 33 are bolted rigidly to the arms 30 and 31 and hand screws 34 are mounted in these plates for engaging the article to be operated upon and mountain; sheari g '10 aiidin' aheid e as;
